Nattokinase Purification and Concentration Equipment - Nattokinase Membrane Separation Equipment

Expert in Nattokinase Membrane Separation Equipment, Setting New Standards for Fibrinolytic Activity

With the surging demand for cardiovascular health and antithrombotic drugs, Nattokinase has become a star ingredient in the biopharmaceutical and health product industries due to its high fibrinolytic activity and natural safety. However, traditional production processes face challenges such as enzyme activity loss, impurity residues, and low concentration efficiency, which severely limit product purity and market competitiveness. Xeehe Fluid Technology, with its independently developed nattokinase membrane separation, purification, and concentration equipment, offers manufacturers a full-process solution featuring high-precision separation, low-temperature activity retention, and energy-saving benefits. This helps clients overcome technical bottlenecks and establish industry benchmarks for "high activity, high purity, and low cost"!

I. Industry Challenges: Why Do Traditional Processes Struggle to Meet Stringent Standards?
Nattokinase production requires efficient extraction from fermentation broth while preserving its fibrinolytic activity (FU value). However, traditional technologies suffer from three major drawbacks:
- Severe enzyme activity loss: High-temperature evaporation and salting-out precipitation cause enzyme denaturation and inactivation, with activity retention rates ≤70%;
- High impurity residues: Centrifugation and chromatography methods struggle to remove杂蛋白 (e.g., residual Bacillus subtilis proteins), with purity often below 85%;
- High costs: Multi-stage purification steps are complex, solvent consumption is high, and production costs exceed ¥100,000 per ton of enzyme.

Xeehe Fluid's membrane separation technology addresses these issues through a "low-temperature screening-targeted retention-efficient concentration" process chain, leveraging physical separation principles to achieve breakthroughs in both fibrinolytic activity and production efficiency, redefining nattokinase production standards!

II. Xeehe Fluid's Technical Advantages: How to Achieve a Leap in Fibrinolytic Activity?
1. Three-Stage Membrane Process Chain for Full-Process Precision Purification
- Microfiltration (MF) for菌体 removal: Ceramic membranes (0.1μm) rapidly eliminate Bacillus subtilis and suspended particles, with enzyme recovery rates ≥99%;
- Ultrafiltration (UF) for targeted retention: 50kDa ultrafiltration membranes precisely separate nattokinase (molecular weight ~28kDa), achieving杂蛋白 removal rates ≥95% and purity levels ≥90%;
- Nanofiltration (NF) for low-temperature concentration: Gentle concentration of enzyme solution below 40°C increases solid content to 20%-25%, with enzyme activity retention rates ≥98%.

2. Low-Temperature Activity Retention with Fibrinolytic Activity (FU Value) Retention ≥95%
- Entire process temperature ≤40°C prevents破坏 of enzyme spatial structure, ensuring fibrinolytic activity (FU≥20,000/g);
- Purely physical process eliminates chemical residues like ammonium sulfate, complying with USP and JP pharmacopoeia standards.

3. Energy Savings and Cost Reduction, Cutting Overall Costs by 50%
- Energy consumption reduced by 60% compared to traditional evaporation processes, with processing costs ≤¥50,000 per ton of enzyme;
- Wastewater reuse rates ≥80%, COD reduction ≥90%, helping companies achieve GMP and ISO14001 certifications.

III. Application Scenarios: How Membrane Technology Empowers Nattokinase Production
1. Fermentation Broth Pretreatment
- Challenge:菌体 residues interfere with purification, centrifugation is inefficient and prone to contamination;
- Solution: Ceramic microfiltration systems increase processing capacity by 3 times, with enzyme solution transmittance ≥95%.

2. Enzyme Solution Refinement and Purification
- Challenge:杂蛋白 molecular weights are close to the target enzyme, making chromatography costly;
- Solution: Ultrafiltration membranes precisely retain nattokinase, achieving purity above 90% and reducing chromatography steps by 50%.

3. High-Activity Enzyme Powder Preparation
- Challenge: Traditional drying processes cause enzyme activity decline;
- Solution: Nanofiltration concentration + freeze-drying increases enzyme powder activity (FU/g) by 30%, with 100% solubility compliance.

IV. Xeehe Fluid vs. Traditional Processes: Data Demonstrates the Technological Gap
| Comparison Item | Xeehe Membrane Process | Traditional Salting-Out Process |
| Enzyme Activity Retention | ≥95% | ≤70% |
| Production Cycle | 8 hours | 24 hours |
| Cost per Ton | ¥50,000 | ¥120,000 |
| Environmental Impact | 90% wastewater reduction, zero chemical additives | Difficult high-salt wastewater treatment |
